MQ60, MQ120, & MQ140 CNC Quill Feed Units

Standard Features

The MQ-60, 120, & 140 units are ball screw actuated variable feed, quill type machining units.  They are ideally suited for single or multiple spindle applications on all types of metal removal machinery.  The unique arrangement of few moving parts in a compact assembly provides for versatility of application and minimal maintenance in operation.  Each unit features a large 4.250” dia. hardened and ground quill which carries the spindle assembly and the ball screw nut.  The excellent quill bearing area, combined with the ball screw centerline thrust design, provide for extreme stability throughout the unit stroke.  A CNC servo motor drives the ball screw and controls all functions of rapid traverse and feed. 

The flexibility of this drive is evidenced by the many cycles that can be easily obtained with the available control options , such as multi-stage feed, back feed, pulse feed (chip breaking), gap jumping, peck feed, and rigid CNC tapping thru synchronization of the feed and spindle motors.  Standard, quick-disconnect proximity switches control the home position and over-travel limits.   Internal bumper cushions mechanically protect the unit from over travel damage in both directions.

Standard Controls

Single axis CNC control components or pre-engineered systems are available from 5 to 10 HP for drill stations.   Dual axis, CNC control components or complete systems are available for tapping stations.   The dual axis controls apply to both drilling and tapping operations or combination drilling and tapping cycles for use with combination drill/taps (draps).   Standard CNC rigid tap cycles include left or right hand threads and inch or metric pitch.   All cycles are stored as sub-routines in system memory and recalled thru PLC or HMI interface (multi-tasking).
